invention krelates to an improved i' mechanism for vcalculating maer ind more particularly to novel means r loc ng such mechanism in position.

mechanism is of the kind deent #9?260 granted to me $1@ and in. a (jo-pending applit i vie Getober 21st, 1911under This transfeiwmechaf essentially a finger coping h a. ciphering mechanism, which brought into alinement with a ng ciphering mechanism `whenever the transfer is to be made for the purpose of lhrming' the desired carrying or bor ng oit tens, hundreds, etc., as fully dis- -d in the above citations.

relatively fixed toothed sector 11 .which receivesrntary motionthrough a mlter wheel i2 and transmits said motion 4to the c1pher- -ing mechanismjproper. Upon shaft. is slidably' and fnon-rotatably mounted a mutinted harxvell that cooperates with a scalicncd lrotary diskv 14' thereby prevent-ing the latter from accidentally rotating, while the parts '13, 14v are in operative engagement'. IBar'el 13 is'provided with a grooved hub 'wlliich' isfehgaged by a fork 16 rigidly seeure( The latter isrecessed as at 18 for the recep- 5 tion 0f one.v endof a spiing-inuenced s hip@ ping' lever 19, the other end of which 1s en-H .thed wheel cooperating with lthe adjoin-v le present invention provides novel and. ctive means for preventing an accidental 1Upon a squared shaft 10 is mountedia' muy@ axially reciprocable Arod 17.-

. ment 23Ecan"unobstructtj i gaged by a trigger 20. Hub l5 is provided wlth a radial. transfer finger 21 and with a helical cam 22 adapted to be engaged by a fixedv abutment- 23. Finger 21 is adapted to vmesh into a toothed mount-ed with disk 14.

Whenever during the course of operation' ofthe machine, motionrv is to be transferred from shaft 1() to. thatof wheel 24,-

trigger 'is swung toward partition 25, so

as to tilt-lever 19 and thereby'move rod 17 backward (Fig. 1). Thus fork. 16 will.

cause barrel 13 to participate inthis movcment, whereby barrel 13 is' withdrawn from underneath scalloped disk 14 While vfinger 21 is brought into alinement with gear wheel 24, all as fully described in, my above cit-ed patent and so-,pending patent appli- '75 cation.

As the' parts hereabove referred to i are liable to be subjected to comparatively severe shocksduring the o eration of the machine, which shocks mig t tend to dislodge said parts, 'means `are provided for positively preventing a return of barrell and finger 21 to ltheir original positions 4'until aV meshing between said finger and wheel 24. has taken place, thereby insuring areliable operationl of the. transfer mechanism.- These means are shown to consistof a latch.

wheel' "2 4 *ecard-allyl oscillate on a lheaded study 28 secured-to lpartition-25 by a screw 29. Latch 26 is. perforated as at 3Q for the reception of one end of a coiled spring 31, the other. end of f which is secured -to a pin 32 extending out vward from stud 28 through corresponding slots 33 of sleeve 27, said pin also serving' to limit the play ofthe latch. The latter rests normally on the unmutilated section of barrel 13,-but' as soon as the latter has been shifted backward for transferring purposes, latch 26 slips oil t-he'barrel owing to the action of spring 31, thereby temporarily locking the barrelv against return movement. The relative position of the .parts 1s such4 that prior tof-and duringtheengagement of v linger 2l with wheel 24, latch 26 is .located in front of` the forward edge of theV un1nutilated section of barrell, so as toprevent the latter from' movingforward. As soon as the engagement between the parts'21, 24

vhas taken place, the mutilated section '34 lfb-barrel 1 3 forward. Thus during the last' stage of the' rotation oi the barrel, the latch will ride up. on' the edge 35 thereof, thereby returning` mounted thereon, means for shifting said ringer on said shaft, 'and meansV for' locking the finger against return to its initiaLposition.
